Answer:
[tex]\fbox{\begin{minipage}{12em}5768 is not divisible by 3\end{minipage}}[/tex]
Step-by-step explanation:
(1) Check the theory:
To test a number is divisible by 3 or not, we simply get the sum of all member numbers, then we check this sum is divisible by 3 or not.
If this sum is divisible by 3, the original number is divisible by 3 as well and vice versa.
(2) Apply the theory in solving the problem:
Let's see the number 5768:
Taking the sum: 5 + 7 + 6 + 8 = 26
26 is not divisible by 3 => 5768 is not divisible by 3.
(3) Double check:
5768 = 1922 x 3 + 2
Hope this helps!
